1. This means that the consulate sent the case back to USCIS for review, revocation (and may be investigation of the employer). Usually, you should not have any issue with it. But from what I recall, if the case is revoked, you will be subject to the H-1 quota in future.

2. I do not see any implications for the individual unless the revocation was based upon some problem with the individual's qualifications.

Status, authorized period of stay and unlawful presence are three VERY important concepts in US immigration laws with far reaching implications. The nuances in these concepts are so intricate that they can trip up even my fellow-lawyers. I see issues in this all the time.

Here is a brief primier to enable you to understand the basics. This is by no means an exhaustive analysis.

The cardinal rule in visas is that consulates can ask for pretty much anything. If they do ask for proof of H-1 employment or pay stubs and you do not have it, the H-4 still cannot be denied. The fact that one has been out of status is no bar to the grant of an H-4 visa.

1. My story begins like this: I was working for company A, got stamping in May2007(in canada). Came back to US, changed to company B. Got laid off on Feb 27th, 09. In order to have a valid status I got married on Feb 15th and got my H4 legally on March 20th, 09. Two weeks back a miracle happened, got a job through company C and applied for PP H1b, received it last Thursday. Now, I am planning to go to India for a week in June, 09. Tough having a valid H1b stamping prior to the H4-H1, do I still need another H1b stamping?
